Starting from solving the main limiting factors of the project, CCPM overcomes the shortcomings of traditional scheduling methods in just considering the logical relationship between processes and the duration redundancy of activities, and it is especially good at schedule optimization. However, few researches are conducted applying CCPM to urban rail transit project. Considering the complexity of rail transit projects, this paper applies CCPM to the schedule management of urban rail transit project. By taking the construction of one station in Zhengzhou rail transit No.1 line for empirical research, the basic procedure of applying CCPM to rail transit project schedule management is introduced, and the critical chain method optimizes the project schedule to a certain extent. This paper provides a more comprehensive description of applying critical chain method to urban rail transit project.
